I am considering getting some fiddler crabs (or red claw) because I have an empty ten gallon tank that is screaming at me to use it. I know they are brackish water and that they need to have part water and part land but am not able to figure out how deep of water they need and if it should be 50/50 or what. Any help would be great! Also, for the land part would they prefer gravel, solid rock (like a big flat piece) or sand. I have several ideas in my head on how to do this but haven't been able to find much information on them.
Thanks in advance!

Hmm...I haven't been able to answer the water depth question. I think I might pass on these guys for the time being. The tank is going in my toddler's room and she didn't seemed too impressed with them at the lfs. She did like the dwarf aquatic frogs so I might get those. The tank setup would be easier...
 
I was contemplating doing a setup with the mudskippers and crabs back when I had a mudskipper 5 or 6 years ago, but I never got past the research stage as I didn't have the space. I agree that most skippers get large enough to eat the crabs, but I figured if you get a 6' tank for example, and add enough land portions you might get away with this. a tank that size also gives a little more of a water area for other possible fish. My mudskipper was in a 30 long at the time and I didn't have any of the larger tanks available to try and see if this would work.
 
I have two fiddler crabs in a 10g with a pile of shells and gravel in the corner for land. The tank has about 2-3 gallons of water in it. I don't think water depth is as important as quantity of water. If the water is 5-6" deep, they'll just have to climb more to get to the land. I heard, when I got mine, that 1-2 g per crab is a relatively common measurement. Red claws I don't know anything about, unfortunately.
